Title: Improvements in or relating to apparatus for dispensing liquids
IPC: B67D1/00
Filed: 1946-04-30
Abstract: 634,568. Dispensing mixed drinks. COCA-COLA CO. April 30, 1946, No. 13024. Convention date, June 27, 1945. [Class 116] [Also in Group XXVIII] Apparatus for dispensing carbonated water and syrup comprises a carbonator 50 connected to a source of compressed carbon dioxide by a pipe 60 and having a special capillary nozzle 46-51 as described and claimed in Specification 608,018 and a syrup pump assembly 24, 25, disposed in a syrup tank 48 and operated by the carbon dioxide gas pressure through a pipe 49 and solenoid operated valve 55. A second solenoid 52 controls the discharge of carbonated water by opening and closing the valve 53. The syrup pump assembly (Fig. 2) comprises a pressure sac 10 filled with liquid and adapted to be deflated by the gas pressure acting on its outside surface, a working sac 11 also filled with liquid which on inflation operates a piston 37 to pump syrup in a chamber 36 through the pipe 44 and check valve 45 to the nozzle 57, and a metering spindle 13 through which liquid passes on deflation of the sac 10 to inflate the sac 11. The spindle 13 has spiral capillary grooves 16 through which the liquid passes, the length of which can be adjusted, to control the rate at which syrup is dispensed for a given gas pressure, by screwing the spindle 13 up or down in its housing 14. A rubber diaphragm 40 and spring 42 cushion the action of the pump. At the end of a dispensing operation valves 53 and 55 shut, the shutting of the valve 53 allowing the pressure in the pipe 49 to drop to atmospheric through the pipe 56, the bottom end of which, during dispensing, was exposed to the full pressure of the carbonated water. The spring 38 thereupon restores the piston 37 to its upper position, drawing in fresh syrup from the tank 48 through check-valve 33 to the space 36 in readiness for the next operation. Liquid is rapidly returned from the sac 11 to the sac 10 through a central bore in the metering spindle and a check flap-valve 21, 22, closed during a dispensing operation. In a modification (Figs. 10 and 11, not shown) the pressure and working sacs 10, 11, are separated and communicate through a pipe. In a further modification the pressure sac and metering spindle are dispensed with and the gas pressure operates directly to inflate the working sac 11. Specification 632,574 also is referred to. The Specification as open to inspection under Sect. 91 states that the capillary grooves 16 may be " hydraulically identical " with those in the nozzle to ensure a constant relationship between the quantity of syrup and carbonated water dispensed. This subject matter does not appear in the Specification as accepted.

Filed: 1953-05-12
Abstract: 764,064. Jet propelled rotary wing aircraft. NAPIER & SON, Ltd., D. May 4, 1954 [May 12, 1953], No. 13300/53. Class 4. [Also in Group XXVI] A power plant for a helicopter comprises a gas turbine plant, Fig. 1, generating combustion gas which passes by way of a rotary valve 15 as described in Specification 764,063 and a duct 16 to the nozzles of the jet-propelled rotor of the helicopter. In another position of valve 15, the gas is discharged through a duct 17 to exhaust or to a straight jet-propulsion nozzle. The gas is generated in combustion chambers 3 and, after traversing a turbine 4, passes to the valve 15 between cylindrical walls 18, 19, Figs 3 and 4, and is guided into a rectangular duct 20 by means of two guide vanes 27, one on either side, which extend from a single vane 28. In addition, there is a guide vane 29 having curved extensions 30, 31 which extend in a generally horizontal plane towards the discharge end of the turbine 4, and a vertical portion 32 which extends across the duct 20. A vertical partition 35 divides at its lower end into two curved or straight walls which are united to the wall 18. A compressor 5 draws in air through an intake 6 and discharges it into the space between the wall 19 and an outer cylindrical wall 21, where it is guided upwardly by two guide vanes 24, one on either side of the wall 19, into the space between the duct 20 and a further rectangular duct 22. Thus the hot gas from the turbine is jacketed by a stream of cool air which prevents overheating of the valve 15. This jacketing may be retained downstream of the valve. The compressor 5 and a compressor 1 which supplies air to the combustion chambers 3 are both directly driven by the turbine 4.

Abstract: 470,997. Securing milk - bottles &c. to doors. JAMIESON, J. N. May 12, 1936, No. 13469. [Class 44] A device for securing milk-bottles &c. to doors comprises a plate 3 secured to the door 1 and provided with an aperture in which the neck of the bottle 5 may be inserted, a pair of jaws 7 pivoted at 6 being adapted to move inwards and grip the bottle. Jaws 7 are opened and closed by sliding movement of a bolt 10 which passes through the door, the bolt having a square stud 12 which co-operates with crossed slots 8 formed in the jaws. The bolt is moved outwards to open the jaws by handle 9, and is retained by engagement of a pivoted catch 15 engaging, a notch 16. Insertion of the bottle raises the catch, whereupon the bolt 10 is pulled inwards to close the jaws in the bottle by a lever 22 with a counterweight 23 and having pin- and-slot connection with the bolt. The pin 20 may be placed in any one of a series of holes in the bolt, to allow use with doors of different thickness. A pawl 26 loosely mounted on the pin, rides over teeth 25 on the lever as the latter falls, but engages the teeth to prevent the bolt from being pulled out to release the bottle from outside, until the pawl has been directly disengaged from inside. If catch 15 be released in the absence of a bottle, lever 22 falls to such an extent that a cam surface 27 on the lever throws pawl 26 out of engagement, so that the device may be reset from outside. The slots 8 have teeth 13 co-operating with the edges of stud 12 and serving to prevent accidental opening of the jaws if the door be opened suddenly, after the bolt has been released from inside. A plate 17 is fixed to the door to cover the mechanism. According to the Provisional Specification the jaws may be operated by link connection with the bolt.

Title: Improvements in or relating to tone control systems
IPC: H03G5/08
Filed: 1958-04-29
Abstract: 892,466. Tone controlling; volume expansion. TELEFUNKEN G.m.b.H. April 29, 1958 [April 30, 1957], No. 13501/58. Class 40 (4). [Also in Group XL (c)] A tone-control system comprises switching means for effecting different tone adjustments, said switching means also controlling the contrast expansion. As shown, the incoming signal after amplification at 1 is applied to a potentiometer comprising resistor 3 (and possibly 4) in series with the anode cathode path of valve 6 whose conductivity is varied in accordance with the amplitude of the output signal from valve 1, which is amplified, rectified and applied in a negative sense to the grid of the valve 6. The signal thus expanded is applied to an amplifier 19, 20 whose feed-back path is provided with four-position ganged tone control switches 24, 25, 26 to produce the various tone conditions. Ganged to these switches are switches 16, 17 arranged to change the contrast expansion conditions. Thus, switch 16 either includes or omits resistor 4 from the potentiometer comprising resistance 3 and the variable impedance of the valve 6, so varying the degree of contrast expansion. Switch 17 controls the value of the potential applied to the grid of the valve 6 and hence the value at which the valve 6 cuts-off, i.e. the value of the input signal at which contrast expansion ceases. The switches may be replaced by four pushbuttons. The invention may be applied to radio-receiving apparatus or reproducing apparatus.
